Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

Guard declarations of 'sve_{vq,vl}_from_{vl,vq}' macros on Aarch64 (and unbreak build)
Commit 122394f1476b1c925a281b15399119500c8231c1 ("Function for reading
the Aarch64 SVE vector length") has added macros to manipulate SVE
vector sizes based on Linux kernel sources, but did not guard them
with #ifndef's, which breaks the build when the system headers already
have these macros:

Guard declarations of 'sve_{vq,vl}_from_{vl,vq}' macros on Aarch64 (and unbreak build)
Commit 122394f1476b1c925a281b15399119500c8231c1 ("Function for reading
the Aarch64 SVE vector length") has added macros to manipulate SVE
vector sizes based on Linux kernel sources, but did not guard them
with #ifndef's, which breaks the build when the system headers already
have these macros:
